There is no local install, no CLI to configure, no MCP server to run yourself. The sandbox environment that backs the
connector is pre-provisioned for the class — your Project, your Template, and your Notation all land in your isolated
tenant. They will still be there after class so you can revisit and revise.
This is a hosted-connector instruction, not a local KIND instruction. Gemini must be able to reach the configured A2A
endpoint and complete its Google/OIDC setup; a worktree's localhost URL is only for the browser rehearsal above and
must not be pasted into Gemini's connector dialog.
